Getting this error when I go to shut down my PC. Access Violation Error ad address 00423B70 in Module Comcast AntiSpy.exe Write of address 0000000D. Running Windows XP and Kaspersky Internet Security 2010. Have downloaded Spy Bot-SD Resident and Malwarebytes Anti Malware to try to fix the problem but it has not worked. Comcast tells me it is becaues I don't use their Norton Package provided with Comcast. I am also running Microsoft Security Essential as I am typing this to try to fix the problem. Any help is appreciated.

I would try and uninstall Nortons completely using their own Removal Tool.

You will see a link there for "I have a product that was purchased from my service provider".

It seems likely that when you uninstalled this Comcast provided Norton utility it didn't all uninstall properly.

Just a note. We find that Spybot often doesn't work with today's anti-virus scanners and we don't recommend it. Also, you say you are using Kaspersky Internet Security 2010 as well as Microsoft Security Essentials. They may be conflicting.

(ALWAYS RUN AND SAVE SYSTEM RESTORE POINTS BEFORE AND AFTER INSTALLING OR UN-INSTALLING ANY CRITICAL COMPONENTS OR SOFTWARE!!)

Besides the fact that running multiple firewall or spyware guard and removal programs together will conflict with each other; different defense programs have, or search for signatures related to attacks. Something listed by one of these programs can easily show up as an attack or initiate a defense or (Access violation) and cause itself or another program to stop working properly or not at all.

Example, older versions of Spy-bot would list "file sets", or versions of attacks in a file that Spy-bot protected against, While older versions of Norton for example would see these and warn or initiate a removal of that reference. The actual file or program was nothing more than a reference in your registries and or settings of Spy-bot (advanced mode).

Comcast customers who use Norton 360 (Comcast version) should note that: Windows firewall, Windows Live Essentials, and other firewall or spyware removal programs can cause the same dilemma if run together or at the same time. One of the reasons why you are asked to disable or close these programs while installing any other number of programs is to prevent some of these same occurrences.

My suggestion to you before deciding one program or another is useless or better than another is to decide which ones you want to use. You need firewall and virus intrusion or protection software. Some combinations of these will or won't work together. In my experience, Norton and Spy-bot work well together under most circumstance if they are the only Two you use. Although, installing Spy-bot first before Norton allows Norton to recognize newer versions of Spy-bot as a form of virus protection and from there their default settings works well. Installing Norton first does not always work the same. Norton 360 all by itself without spy-bot, Live essentials or Windows software has all the features you need if you know where to look, (Registry Cleaner, Program removal or disabling, backup services and more). Spy-Bot does not have a couple of these features so I include "CCleaner" from Piraform, not File-Hippo. File-Hippo wants you to wait and offers other software you may not want.

So for me, your programs may differ but the result is the same, I would first download and save the install program and not install right away the programs I want to use. I would then, disconnect from the internet or network you are on to avoid intrusions or attacks. If you have these or multiple similar programs installed or running, I would then completely shut them down or disable these programs and background processes so that uninstall will be unhampered and more complete.

["CCleaner" is a good program for closing any and all running processes via it's "Tools" section and then "Start-up". Programs can be disabled or removed as well from the "Uninstall" tab in tools. This is also a great program for cleaning your registry entries, temp files, and various settings of software saves. BE SURE TO BACKUP AND SAVE BEFORE AND AFTER CHANGES JUST IN CASE ]

I generally install in this order for my choices, CCleaner, Spy-Bot, Then my Norton products. I disable or don't use at this point, Windows firewall, or the security section of "Live Essentials" unless these are my choices, then I would only use CCleaner, Spy-Bot, and then install or re-install the other software I choose in that order. Spy-Bot needs to have updates first, then a full scan of your PC, then immunization ran to protect your remaining software in your system before continuing installs of your chosen Programs. Both CCleaner and Spy-Bot for Windows 7 especially need their .EXE file properties set to run as Administrator first in order to work completely and properly.

All other settings in advanced modes for these programs are generally safe and should not be changed without specific knowledge of how to use them.

In conclusion, Clean, Fresh installs usually solve these issues when done correctly. Continue to install your Firewall/virus-guard software and then reconnect to your network or internet to get further updates. Finally, run any last scans to get a good starting reference point.

It took me HOURS to track down a solution to what was to me a real HEADACHE. Not only was it swollowing up my 4 core CPU but it was preventing me from closing down my PC without first canceling a big Green and RED ERROR message. You most likely added A COMCAST tool bar to your PC containing this AntiSyp.exe. Go to your CONTROL PANEL and using ADD/REMOVE DELETE that COMCAST TOOL BAR and your problem is solved. PS: Comcast has never heard of AntiSyp.exe. I hope this helps.

I have finally found a solution for this nuisance. If you happen to have Norton Security Suite on your computer,go to Startup Manager and comcastantispy.exe should come up.Turn it off and then click on it once.Then hit ctrl,alt. and del. at the same time.This will take you to processes section.Scroll down until you find comcastantispy,click on it and then click on end process and this should end the problem,I know it did for me and I hope it works for you because I know it has been a nuisance for me for quite awhile. Good Luck

Had this problem myself. I had the comcast toolbar. I had uninstalled the toolbar, but it left the antispy. To remove it I used crtl-alt-del to access the task manager then clicked the process tab and browsed through until I found it. I right clicked it and selected "open file location" and inside the folder there was the program (duh) along with an uninstaller. I used the uninstaller and it is now gone.

My friend had this problem last week, it takes me six hours to look around on google to fix this problem, I found this blog provide a useful information to fix comcastantispy.exe related errors: how to fix comcastantispy.exe error.
